Young athletes are still growing and it is important for them to have an adequate intake of energy that includes carbohydrates, proteins, fats, vitamins and minerals. Insufficient intake can lead to celldamage, weight loss, worse performance and a higher risk for colds or sports injuries. Young girls are at higher risks with an insufficient intake because of the female athlete triad. Iron is one of the most important mineral and helps with the oxygen transport when it is combined with Hb. Iron sufficiency is the most common nutrition insufficiency in the whole world. Approximately all oxygen within the red blood cells binds to Hb and enables oxygen transport within the blood. One gram of Hb binds to 1,34 ml O2. C-vitamin helps the absorption of iron, while as thee, coffee and wholemeal prevents it. Anemia is common in athletes and specifically women because of menstruation. Anemia leads to inferior oxygen transport and causes an impaired performance. The aim of this study was to examine the effects on blood count, fat mass, gender and type of sport of 16 year old students in high school with sports focus. The material that we have used is from an ongoing research that includes 91 young athletes and the significance level is 0,05 in this study. The results show that boys have higher Hb than girls and that girls have more fat mass than boys. It also show that six persons have anemia (less than 120 g/L Hb in women and less than 130 g/L Hb in men). Hb, ferritin, fat mass, EPK and EVF are significant between boys and girls. Surprisingly do not iron differ between the genders. The results also show that the adolescents have a good fat mass and that fat does not correlate with blood count. Measuring serum ferritin can give you valuable information about iron stores in the body and if you are iron insufficient. There are many discussions about low-fat diets and how that can be bad for the body and the performance. Low-fat diets are usually found in athletes where the weight is of importance. That is not the issue in this study. Other studies show a connection between low body fat and worse performance in elite endurance runners. Other studies have also found that anemia is more common in athletes than non-athletes.
